// dear imgui: Renderer Backend for SDL_Renderer
// (Requires: SDL 2.0.17+)
// dear imgui: Renderer Backend for SDL_Renderer for SDL3
// (Requires: SDL 3.0.0+)
// Important to understand: SDL_Renderer is an _optional_ component of SDL.
// Note how SDL_Renderer is an _optional_ component of SDL3.
// For a multi-platform app consider using e.g. SDL+DirectX on Windows and SDL+OpenGL on Linux/OSX.
// If your application will want to render any non trivial amount of graphics other than UI,
// please be aware that SDL_Renderer offers a limited graphic API to the end-user and it might
// be difficult to step out of those boundaries.
// However, we understand it is a convenient choice to get an app started easily.
// please be aware that SDL_Renderer currently offers a limited graphic API to the end-user and
// it might be difficult to step out of those boundaries.
// Implemented features:
// [X] Renderer: User texture binding. Use 'SDL_Texture*' as ImTextureID. Read the FAQ about ImTextureID!
